The catch is that there is little evidence that Republican voters are isolationist or opposed to helping Ukraine. According to a Pew Research poll from May, 71% of Americans and 68% of Republicans support sending military equipment and weapons to Kyiv. Sixty-four percent of Americans and 60% of Republicans favor stationing U.S. military forces in North Atlantic Treaty Organization countries near Ukraine. These numbers persist despite voters’ anxiety about nation-building and so-called endless wars.

The GOP can—and should—address these concerns by taking a few steps. First, it should make sure that aid is purposeful and not open-ended. The Biden administration’s slow decision-making and overcautiousness have rightly spawned concerns that the U.S. is sending just enough military assistance to foster a stalemate. The president has invested U.S. prestige in the conflict, and Republicans should be concerned if the administration isn’t aiming for a decisive win. With a new majority, House Republicans would be well-situated to exercise vigorous oversight. Press the secretaries of state and defense for their strategy—and insist that they come to Capitol Hill often to defend it…

Republicans should be against open-ended commitments, subsidies for broken international agencies, and funding that constitutes nation-building. But there is space well short of cutting aid to Ukraine for a GOP policy that holds the Biden administration accountable while strengthening U.S. strategic goals in Europe and Asia.
